Retirement and forum shutdown (17 Jan 2022)

Hi,

John Howell who has managed the forum for years is getting on and wishes to retire from the role of managing it.
Over the years, he has managed the forum through good days and bad days and he has always been fair.
He has managed to bring his passion for fish keeping to the forum and keep it going for so long.

I wish to thank John for his hard work in keeping the forum going.

With John wishing to "retire" from the role of managing the forum and the forum receiving very little traffic, I think we must agree that forum has come to a natural conclusion and it's time to put it to rest.

I am proposing that the forum be made read-only from March 2022 onwards and that no new users or content be created. The website is still registered for several more years, so the content will still be accessible but no new topics or replies will be allowed.

If there is interest from the ITFS or other fish keeping clubs, we may redirect traffic to them or to a Facebook group but will not actively manage it.

I'd like to thank everyone over the years who helped with forum, posted a reply, started a new topic, ask a question and helped a newbie in fish keeping. And thank you to the sponsors who helped us along the away. Hopefully it made the hobby stronger.

I'd especially like to thank John Howell and Valerie Rousseau for all of their contributions, without them the forum would have never been has successful.

Thank you
Darragh Sherwin

hi all

i'm sure this is very normal
but i dont know any better!

i have a 36w x 12d x 15h tank
and its been full for 3 days

i have a perspex lid cut exact size for it and only tonight i noticed the bow in the front of the tank while trying to sit the lid on, its nothing dramatic, its about 4mm, but quite tenoticeable when trying to fit a perfect rectangle lid on top.

im sure this is normal but would like someone to reassure me, i dont fancy 96l of water on my floor!

Is it just 4 pieces of glass siliconed together or is there any corner bracing or is it on a stand with a lip around the bottom? Im guessing from the perspex lid that it doesnt brace the top.

A pic would be handy ;)

My tank has a bow in it as the last owner decided to cut a brace out of the top of it so I replaced it but of it cracks its 300L of water and a couple of hundred quid of fish I would get over it if it did break but the other half wouldn’t :unsure:

:unsure: :ohmy: :ohmy: :huh: :silly: :silly: :blink: :blink:

hi guys

i dont have a specific pic of the bow
will post one shortly but see general pic of tank below

its a clearseal tank with the usual
4 pieces of glass siliconed together
sitting on a base

its actually a used tank from a member here
but i removed glass fins they had running the length of the tank to sit glass lids on

Im sure its fine as its a known brand
and is built braceless as far as i can tell



cheers

The glass strips you had running the length (width) of the tank were actually to add rigidity to the glass front and back of the tank, the fact that the lid sat on them was merely a convenient 'extra'...I have to say the removal opf them was a mistake.

My suggestion would be to lower the tank water level to an extent where the bow is less significant then re-silicone the strips back, you can use G-cramps or similar to hold them tight to the front and back glass while the silicone cures and dries.

I had to do this on an old tank which the silicone holding the rigidity strips had become unattached and it worked fine - it's still holding over a year on.

thanks john

the strips were added by the previous owner
as a holder for the glass lid
and were not on the tanks when manufactured

I was talking to them since buying the tank
and told tehm in passing that i had removed the strips
and they never said anything about them being structural
(i will double check)

i have read before about the bigger juwel tanks
bowing considerably, but this tank is not big

I thought when i posted this i would get about
100 replies saying "dont worry, mine bows too"

HI 4,
I would follow Johns advice asap.

www.clearseal.com/aquariums_standard_basic_first.htm

in these tanks you can see the line on the black trim were the bracing glass is.

was there a black or coloured trim removed????

one should always consult manufacture before removing anything like this that might compromise tank safety.

thanks all

mickey: god bless your eyesight!
i cant see it from that image

the braces i removed were rough and ready
and looked very DIY, blobby silicone and chipped rough edge glass strips, so i thought they were added afterwards

I have asked the original owner about whether
they put them in or if they were there,
i also asked clearseal in an email
hopefully they will both get back to me,

i think i will dump half or more of the water when i get home,
theres no stock in the tank anyway

i'm "bulling", the tank looks way better without them
and it took me ages to get them off!

Regards

I would have expected the bow to be a little bit more than 4mm. A tank 36x15 high would normally have a bow of about 5-8mm with 6mm glass without braces. Of course this varies on the quality of the glass.
As far as i know clearseal usually put braces on so they can use thinner glass and cut down on the cost of manufacturing.
I wouldn't be worried about a 4mm bow.

cheers platy

i have since found a decent photo of another clearseal on the web
and the braces are there!

i was sure it was a diy job!

i would love to leave them out
but i wouldnt feel comfortable
now i know they should be there,

so that brings me to my next problem
that i have a new planted tank
that i have drained the water to a level
where i will be unable to filter and heat
or inject co2 and stick these braces back in and clamp there with g clamps for a couple of days

the tank has been full for only 4 days
but was getting filtration, ferts, heat and co2 now it'll be getting none of the above

will my plants suffer big time
with this big change, i have about four inches of water in it,

dont know what to do

4 I wouldn’t worry about it too much if the tank didn’t fail over the last few days it should be fine for another few days, if you half fill it for a few days and leave it running till you can brace it?

As I said my 300L is the same way

It does not have to be a big juwel tank to bow, my 180's and 125 all bow and i know from others here that they do too. However the juwel tanks are designed not to have the braces you removed, where they were installed originally I would definitely not remove them.

Fingers crosssed :-)

4 just put your filter in your other tank to keep it going while you brace the tank.
I would leave off the lights, stop the fertz and stop the Co2 while you stick on the braces.
After 24 hours you can fill the tank again and start the Co2, lights and fertz from scratch. It wont have any negative effect on your plants.

your plants may well suffer over four days of deprivation but u can replace them is it not better to do that than get the mop out and replace the tank

hi all

this has been a self-inflicted nightmare

i reinstalled the braces a couple of weeks ago but one snapped, i had a chat with a guy who used build tanks and he said that
i squeezed too much silicone out by clamping too tight, he said it should have a little play, the tank still bowed by about 1mm after bracing and because the brace was so tight to the glass it was enough to snap it,

so i stripped them out again and reinstalled last night,
now i have gone the opposite way and had too much silicone and one of the braces
was still floppy this evening, so off it came and I will try again tommorrow, all my plants are sitting in a bucket with a heater in it

gosh, that was boring but it may be helpful to the next poor sod who makes a bad decision to remove their braces!

one month on and im back to square one
on my aga entry ;) an unplanted planted tank! ah well , at least i learned something
